Hello guys, I have a Quadro 350s. After a few kilometers (about 200km) there is already a lot of oil in the air filter box. The cylinder head gasket and piston rings were exchanged two weeks ago. I had the problem before the repair, but it was oil water mixture. Valve play was set. No noticeable power loss. The stationary gas fluctuates a bit back and forth. The oil was only filled up about 100km ago, currently again below minimum. The oil which is missing in the air filter box n. The colour of the oil looks like fresh from the canister. Compression was at approx. 12 bar. KM-Stand approx. 40 000km. Cooling water remains constant and no more loss (after cylinder head gasket change). It starts immediately and without mukken. Spark plug picture currently not available, since it is new. What can this be about?
